These modules are designed to upgrade power supplies for both analog and digital circuits, mostly found in CD/DVD/BD players, DACs and similar audio equipment. Substituting the on-board regulators with these regulators improves the sound performance especially in quietness, darkness, resolution and transparency, at a very reasonable price.
Direct drop in / pin compatible of the common LM78xx and LM79xx chip regulators
During operation, we recommend input and output voltage to be >= 0.5V, application DC <=0.7A.
Heat sink is required!
Take extra caution of operating temperature during high current and high voltage operation - apply isolation when using the module - isolate the screw and PCB from the heat sink.
Max voltage <= 35V
Max output current <= 1A
